Purpose : The object of this study is to determine whether QT interval variability in patients with postoperative tetralogy of Fallot increases.
Methods : We enrolled 41 patients who had total correction of tetralogy of Fallot, and 31 healthy controls. They were 6-12 years old. Patients were divided into 2 groups : arrhythmia-positive patients(n=10) who had ventricular premature contractions more than... |

Purpose : This study aimed to characterize the autonomic and chaotic control of heart rate and circadian rhythm in asymptomatic patients with postoperative tetralogy of Fallot(pTOF).
Methods : Twenty-four-hour electrocardiogram recordings were obtained in 30 asymptomatic pTOF patients and in 30 age-and sex-matched controls, aged between 6 and 11 years. The data was digitized and partitioned into sections of 30-... |
